Building on Perth Hills Blocks Takes a Builder Who Actually Works the Slope
Licensed WA builder (BC105853) working across Mundaring, Kalamunda, Roleystone and Serpentine-Jarrahdale. Sloping sites, retaining, and BAL-rated construction — priced transparently with itemized pricing, not buried in variations once the dirt starts moving.
What Hills Sites Actually Need
A flat-block builder pricing a sloping Hills block off a standard template is exactly how site costs turn into surprise variations. Here's what we price in from day one instead.
Sloping Block Design
Split-level and pole-home designs engineered for the site, not fought against it — fewer surprises once earthworks start.
Retaining & Earthworks
Cut/fill, engineered retaining, and drainage priced and disclosed upfront with transparent, itemized pricing — not buried in a variation later.
BAL-Rated Construction
Bushfire Attack Level assessment factored into the design from the start, so window, cladding and eave specs aren't a late redesign.
Areas We Build In
Perth Hills townships and surrounding districts, alongside our regular work across Perth Metro.
